Safety warnings appear throughout this publication in procedures that can harm you if they are

Warning Conventions
Power Supply Warnings
The following warnings apply when you are installing a card or working with the power supply:
Warning
Read the installation instructions before you connect the system to its power source.
Warning
Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning
Ultimate disposal of this product should be handled according to all national laws and regulations.
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitable installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
Warning
Use copper conductors only.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar
with standard practices for preventing accidents. To see translations of the warnings that appear in
this publication, refer to the Regulatory Compliance and Safety Information document that
